MANTLE-SUPPORT.

SPECIFICATION forming part of Letters Patent 1\T0. 637,163, datedNovember 14, 1899.

1 Application filed February 8, 1899- Selial 110- 704,936. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM L. RUSSELL, a citizen of the United States,residing at Duke Centre, in the county of McKean and State ofPennsylvania, have invented new and useful Improvements inMantle-Supports for Incandescent Lights, of which the following is aspecification.

My invention relates to improvements in mantle-supports for incandescentlights, all of which will be fully described hereinafter, andparticularly pointed out in the claims.

The object of my invention is to provide a support for an asbestosmantle having an asbestos loop by passing an asbestos cord or stringthrough the loop and attaching the ends of the string to thechimney-gallery or gallery-posts thereabove.

In the accompanying drawings, Figure 1 is a perspective view of a burnerembodying my mantle-support in its preferred form. Fig. 2 is a similarview of a gallery-ring, showing a modification, in which one end of thestring is provided with a loop and passed over one of the gallery-ringposts and the other end attached to a clip which embraces thegalleryring. Fig. 3 is another modification showing one end of thestring provided with a loop and passed over one of the gallery-ringposts and the gallery-ring provided with a slit to receive the oppositeend of the string. Fig. 4 is a perspective view showing my improvementapplied to bulbs. Fig. 5 is a modification showing the gallery-ringprovided with slits at opposite sides thereof, into which the ends ofthe asbestos cord are passed. Fig. 6 is a View showing the gallery-ringprovided with upwardlyprojecting integral slitted arms. Fig. 7 is a viewshowing the asbestos string attached to all three of the galleryposts.Fig. 8 is a view showing my invention applied to lighthouse-lamps.

Referring now to the drawings, A indicates a burner which may be of theusual atmospheric form, such as is usually used in incandescent lights.B represents the chimney-posts extending from said burner, and O agallery-ring. As here shown, the posts extend through and above thegallery-ring, but in some instances this may not be so; but my inventionis adapted for application to any form of gallery-ring or bulbs.

In the preferredform of my invention I provide clips D, having slittedupper ends a,

the clips adapted to be attached to the gallery-ring at opposite sidesthereof, as illustrated. The mantle G, with which my invention is to beused, is of the asbestos form, which is provided with an asbestos loopH, and I pass through this loop an asbestos string or cord I. As shownin the preferred form, Fig. 1, the ends of this cord are forced into theslits a of the clasps after being passed through the loop of the mantle.

In Fig. 2 I show a modification in that one end of the asbestos stringis provided with a loop b, adapted to pass over one of thechimney-posts, which extends above the galleryring, and the opposite endto be held by one of the clasps, as shown in Fig. 1.

In Fig. 3 I show a modification, in which instance one end of theasbestos string is provided with a loop- (I, and the gallery-ring at apoint opposite the post is provided with a slit 6, into which the otherend of the string is inserted.

In Fig. 4. I show my invention applied to bulbs in incandescent lamps,in which instance the clips are constructed to grasp the upper edge ofthe bulb and to receive the ends of the asbestos string or cord, asshown in Fig. 1.

In Fig. 5 I show another modification, in which the gallery-ring isprovided with slits f at opposite edges thereof, and each end of theasbestos string is inserted in these slits, as illustrated.

From the above description it will be noted that my inventiongenerically consists in passingafiexible support, such as an asbestosstring, through the asbestos loop of a mantle and detachably connectingone or both of its ends to the lamp-gallery, whereby one or both ends ofthe asbestos string may be detached and whereby one or both ends of thestring are adjustable for the purpose of raising or lowering the mantleto have it in the proper relative position to the burner, as is wellunderstood by those skilled in the art.

Owing to the fact that one or both ends of the asbestos cord is,adjustably connected with the lamp-gallery it will be readilyunderstood that the height of the mantle can be readily adjusted bymeans of a flexible asbestos support such as that herein shown anddescribed.

It will also be noted that my invention is adapted to be connected withold forms of burners wherein the posts do not extend above thegallery-ring either by means of the clips, as shown in Fig. 1, or byslitting the edge of the gallery-ring, as shown in Fig. 5.

Asupport for mantles as herein shown and described is very simple andcheap, as well as durable.

In Fig. 6 I show the gallery-ring provided with integralupwardly-projecting arms It, provided with vertical slits t to receivethe ends of the asbestos string or cord. This is a good constructionwhen lamps are specially constructed to receive my flexible support.

In Fig. 7 I show a modification wherein the string for supporting themantle has three ends, each adapted to be attached to one of thegallery-posts. In this event the stringis doubled and twisted togetherto about the center and then moistened with water, which will cause itto stick, and the diverging ends 5 twisted around the gallery-post andthen dampened with water, which will cause them to remain in thatposition by adhesion.

In Figs. 2, 3, and 7 I show my manner of making the string, which is bydoubling the string intermediate its ends to form a loop 6, thentwisting the string together the remainder of the distance. This forms aloop at one end, and the opposite end is adapted to be connected ashereinbefore described and illustrated. The asbestos string in beingtwisted is preferably moistened with water for the purpose of causing itto adhere and to remain in the twisted position,with the loop at oneend, as illustrated in Figs. 2, 3, and 7.

As illustrated in Fig. 8, the floor 8 is provided with the V-shaped slit9, into which the ends of the string can be inserted.

My inventionis also adapted to be used in connection with petroleu m oroil incandescent lights, as will be readily understood, the same as inconnection with gas incandescent lights, with which I have previouslydescribed it.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An improved support for incandescent mantles comprising a mantlehaving at its upper end a sustaining-loop, a string-support at a pointabove the mantle and its loop, a fibrous non combustible flexible stringpassing loosely through said mantle-loop, the end of the string beinglongitudinally adjustably connected with said support whereby the mantlemay be raised and lowered, substantially as described.

2. Asupportforincandescentmantles comprising a mantle havinga projectingsustaining-loop at its upper end, a support at oppo site sides of saidloop and at a point thereabove, a fibrous non-combustible flexiblestring passing loosely through said loop, the ends of the stringbeingdetachably connected with the said support, substantially as described.

3. The combination with the burner hav= ing the gallery-ring, of amantle having a loop, and a flexible non-combustible cord having one endconnected to one side of the ring,

its opposite end of the cord adjustably connected to the opposite sideof the ring, and

passed loosely through the mantle-loop, substantially as described.

I. A mantle-support comprising a mantle having a sustaining-loop at itsupper end, a fibrous non-combustible string passing 8o loosely throughsaid loop, and a support for said string, and clasps for the ends ofsaid string carried by said support, substantially as described.

5. Asupport-forincandescentmantles comprising a clip-support, clipsadapted to be attached to said support, said clips having slits, and anasbestos string having its ends passed in said slits, substantially asdescribed.

6. Asupportforincandescentmantlescomo prising a mantle having a loop atits upper end ,an asbestos string passing loosely through said mantle,the string having a sustainingloop at one end and its opposite endlongitudinally adjustably connected to a support,

and a support for said string, substantially as described.

7. A support forincandescent mantles comprising a mantle having asustaining-loop at its upper end, a support at opposite sides of portsand extending downward at a point intermediate its ends, the ends of thestring being connected with the supports, substantially as described.

8. Asupportforincandescent mantles comprising a mantle having aprojecting sustain- 1 IO ing-loop at its upper end, a support atopposite sides of said loop and at a point thereabove, a fibrous noncombustible flexible string passing loosely through the said loop,
